I applied online. The process took 4 weeks. I interviewed at T-Mobile (Concord, CA) in Aug 2018
Interview
Managers have standard set of questions that they ask every candidate and rushed through few questions. Internal candidates or contractors already working with T-Mobile are preferred. Manager did not take time to share about his team.
Apply for job online, Telephonic interview, If they like on telephone they will call you for FACE TO FACE interview .Background check , Reference will work.
Telephonic interview was the first step. There were a wide array of technical questions . After this came the short list of candidates who were called for a face to face interview. This was a panel interview with technical questions from RF engineers to Directors. After this came the HR round with general questions and also negotiation on salary.
